MASON'S TRIG LINE HOLDER Filed Sept. 6, 1950 INVENTOR ATTORNEYS QPatented Nov. 25, 1952 UNITED s r a s iTET 1 Claim.

This invention relates to a holder designed for use by masons in holdinga guide line when laying brick courses, the line being commonly known asa trig line.

The primary object of the invention is to provide a trig line holderembodying a spring arm which is so constructed and arranged that it maybe readily positioned over a brick and secured thereto by frictionalcontact of the ends of the spring arms with the brick, the trig linebeing removably secured to the holder in such a way that the trig linewill be held taut at all times.

Another object of the invention is to provide a holder of this characterincluding line gripping means which will securely grip the line and holdthe line against sliding with respect to the holder after the line andholder have been properly positioned.

With the foregoing and other objects in View which will appear thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts herein after more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawing Figure 1 is an end elevational viewillustrating the application of the trig line holder.

Fig. 2 is a perspective view of the holder.

3 is a side elevational View of a modified form of holder.

Fig. 4 is a sectional View taken on line ti of Fig. 3.

Fig. 5 is a plan view of one end of the holder, illustrating a springline holding device.

Fig. 6 is a fragmental perspective view illustrating the spring holdingdevice as secured to the line holder.

Referring to the drawing in detail, the holder comprises a body portionindicated generally by the reference character 5, the body portion beingconstructed of a length of spring steel material having one of its endcurved at 6 with its extremity bent outwardly at i, the length of thecurved portion ii being such that it will extend an appreciable distanceover a brick of conventional size.

The opposite end of the body portion is curved downwardly and outwardlyat 8 providing a substantially straight portion adapted to rest on theupper surface of a brick on which the device is positioned, so that themain portion of the body 5 will provide a handle whereby the bodyportion may be readily removed or positioned,

The end 9 extends downwardly and provides a gripping surface at this endof the body portion to cooperate with the curved portion 5 in clampingand gripping a brick on which the holder is positioned. At the inner endof the end portion 9, at a point where the end portion 9 merges with theend of the downwardly and outwardly curved portion 8, is formed thegroove iii through which the trig line extends and in which the trigline is gripped, the trig line being indicated by the referencecharacter A.

As shown by Fig. 3 of the drawing, the holder comprises an arm i i thathas one of its ends extended at right angles to the main portion of thearm providing a clamping jaw i2 designed to fit over one edge of a brickto which the holder is secured, in clamping the brick.

At the opposite end of the arm I i is the pivoted jaw l3 which is formedwith inwardly extended ears M that have pivotal connection with upstanding ears i5 formed on the arm i l.

The reference character i6 indicates an upstanding lug formed with athreaded opening through which the threaded shank I? of the adjustingscrew i8 extends, the adjusting screw cont-acting the inner surface ofthe jaw H3, at a point above the pivot point thereof, so that by movingthe adjusting screw in one direction, the jaw it may be moved towardsthe jaw 82 to securely clamp the opposite side of the brick and hold thedevice securely in place.

Secured to the under surface or at a point adjacent to the innerclamping jaw 12, is a light spring I 9 which is bent upon itselfproviding a spring arm 2t and a stationary arm [9, the stationary armbeing secured to the arm H, as clearly shown by Fig 6 of the drawing.

The spring is iprrned with a circular portion M for the reception of thetrig line used in connection with the holder, the circular portion 2ibeing so designed that when the device is posi tioned on a brick, andthe spring arm 2&3 moves to engage the upper surface of the brick, thearm 28 will move towards the main portion of the spring, securelyclamping the line in the circular portion, holding the line againstslipping.

From the foregoing it will be seen that due to the construction shownand described, I have provided a holder for securing a trig line used bymasons in wall structure, so that the line will be securely held againstslippage after it been properly positioned for a guide.

It will also be seen that due to this construc tion, the line may bereadily anjusted when desired and then secured to the holder byfrictional the arm ii, end of the 3 contact, eliminating the necessityof tying or otherwise securing the trig line to the holder.

Having thus described the invention, what is claimed is:

In a trig line holder, a clamp comprising an elongated body, astationary clamping jaw formed integral with one end of the body andhaving an offset portion, a spring member secured to said body with aportion thereof extending into the offset portion of the body, saidspring member being bent upon itself providing a spring arm extendedoutwardly from the body under which a trig line is positioned, saidspring arm adapted to clamp said trig line upon movement of said springarm by contact with a wall over which the clamp is positioned, and a jawpivotally connected with the opposite end of the elongated body clampingthe body to a Wall.
